Tickets are on sale. You can purchase single session tickets from ticketmaster via TravelZoo Detroit or Travelzoo Indianapolis (code TRAVELZOO). You can also purchase all-session tickets via Ticketmaster. I purchased all-session tickets in Indianapolis for $90 each in the 600 section (at least along the baseline, not corner or behind basket). Just wanted to pass this info along. I hope I didn't pull a massive jinx here. Final Four tickets are just insane and I can only find these hospitality packages which I don't want.
